Maintenance of belt arm

Empty the spark arrester (A) (see fig.: 3.3) to avoid hot sparks damaging or
deforming grinding belt and contact wheel. If the machine is equipped with VFCB-
exhaust unit you must control if the suction channels need cleaning. The dust bag
must be emptied when necessary. The contact wheel (B) needs changing if the
edges are too rounded. The belt must be replaced when it is defective. Change the
graphite pad (C) on the belt arm when necessary.
When changing the contact wheel the grinding belt (D) must be dismounted as
described above. The reverse nut (E) must be dismounted and the flange (F) can
be taken off with the contact wheel (B). The new contact wheel (B) is to be mounted
in reverse order.
3.4

Use of belt arm

Grinding at the belt arm can be done either at the contact wheel or on the grinding
surface. You can also dismount the grinding surface for direct unsupported grinding
on the grinding belt. Let the material touch the grinding belt softly and avoid uneven
grinding as it can damage the grinding belt and overload the motor.
